I'd say even in these samples there's still some errors. The intonation on "brown" in "quick brown fox" is still wrong. "AllHipHop" is not pronounced as a human would, though I'll grant you that's a made-up word so I wouldn't even expect a non-native human speaker to necessarily get that one right.

Still, the quality is such that I'm only observing this in the spirit of scientific analysis. It's some good quality.
